XAML Values

String representation of a Double value equal to or greater than 0.0034 but equal to or less than 160000. An unqualified value is measured in device independent pixels. Strings need not explicitly include decimal points.

qualifiedDouble

A double value as described above, (excepting Auto) followed by one of the following unit specifiers: px, in, cm, pt.

The example also defines a second custom method, called changeColVal. This custom method converts the Value of a Slider to a String and then passes that value back to the ColumnDefinition as the Width of the element.

Note that a separate Extensible Application Markup Language (XAML) file defines the contents of a ListBoxItem.
